Patented Apr. 28, 1931 UNITED STATES PATENT OFFICE PAUL HOB-N, OF STRASIB OURG, FRANCE DEVICE IN SIGNS FOR REMOVABLY FASTENING MOTWIES IO SUPPORTING SURFACES Application filed November 11, 1929, Serial No. 406,495, and France November 30, 3928.

Mv for removably fastening motives to supporting surfaces by providing gritty asperities on me and flexible surfaces on the other of the parts to be assembled.

According to the invention, said gritty asperities consist in a layer of filing, shaping or other metallic chips suitably aflixed to the back of the objects to be fastened and capable of clutching into the fibers of the flexible supppirting surface composed by a fabric or the li e.

Owing to this arrangement, I realize an anchoring which is quite sure and not subjected to any accidental removal.

Moreover this assembling method is of a very cheap character and easily and quickly to be performed. Also from the esthetic point of view, it is satisfying all practical requirements since the most different and various motives may be performed in'an expressive relief.

Several embodiments of my fastening de- 2. A device as claimed in claim 1 and a linvice are shown in the accompanying drawing between the fabric and the supporting ing, in which the same parts are bearing the Surfaces.

gures.

Fig. 1 is a front view of a publicity advertisement which is to be made by putting letters on a card board.

Figs. 2-5 are vertical sections of boards on which motives are fastened in the manner described.

In Figs. 1 and 2, 1 is a rigid board of cardboard, wood or other suitable material covered on the side which is to bear the motives with a preferably coarse fabric (cloth). However there could also be employed a finely woven fabric or a knitting (Jersey or the like). The motives (letters 3) composing for example a publicity advertisement are put on said fabric support. The letters may be made of every suitable material say: metal, cardboard, wood, ebonite, etc. The letter surface which is to come into contact with the supporting surface is roughened by disposing on it a layer of gritty particles 4 consistin of filing or shaping chips of iron, cast iron, ronze, or the like. When the letters are placed on the supporting surface the invention relates to a device in signs gritty asperities thus formed clutch into the fabric 2 and assure a perfect fastening.

In Fig. 3 a lining 5 is inserted between the board 1 and the fabric 2 by which the flexibility of the supporting surface is increased much to the advantage of a most effective fastening of the motives.

The bearing surface ought not necessarily be provided with a rigid back. On the contrary as shown-in Fig. 4 it could also be extended on a wooden frame 6 or the like.

On the other hand, the gritty asperities may also be disposed on the supporting surface and the flexible anchoring ground on the motives to be fastened.

I claim:

1. A device of the character described including a supporting surface covered with fabric and publicity motives having gritty, metallic filings or shaping chips secured on their contact surfaces for engaging the support.
